During the surge, priority was given to addressing potential safety defects and repairing or replacing critical rail infrastructure that affects train speeds and ride quality. Additional regular and preventive maintenance activities were fit in as time permitted. These maintenance activities are and will continue to be conducted on a regular basis during non‐revenue hours to keep the infrastructure in a state of good repair.
Critical tasks accomplished during the surge include:
+ Replacement of over 1,800 crossties
+ Renewal of over 540 insulators
+ Renewal of over 3,100 linear feet of spot rail
+ Inspection and repair of 30 power cables and 24 expansion cables
In some cases, work crews were able to accomplish more than originally planned, such as renewing about 500 additional fasteners and inspecting and repairing about 70 additional Intrustion Detection Warning (IDW) systems. *Rescheduled work: one task remains for traction power +Two junction boxes will be inspected and repaired when crews return to this area during surge 5 at the end of July
*Surge #1 results are preliminary and subject to quality control processes which will remain continuous throughout the duration of SafeTrack. Any remediation work that is
identified will be accomplished during normal maintenance times, without impacting passenger service.
